Power consumption of a Scalextric car

Hi there,
I am setting up a 12 meter (roughly) long track for a local Charity event and it needs to be powered by means other than the mains.
I am thinking of a car battery or a small generator such as this one.

Does anyone know the maximum consumption of power from a scalextric car? I know there are many many variables but I am trying to get an idea of what I need to run 1 car at a time (time trial) one and off throughout a day.

Many thanks,

Back in the '60s a commercial track where I raced was powered by a single standard automotive battery. An ordinary "12 volt" battery in good shape is 12.6 volts when it is fully charged (I just looked that up on Wikipedia). The charging voltage is 13.8 volts, so if you were to measure the battery in a car while it was running it would be more than 12.6 volts. A regular Scalextric "black stripe" motor will try to pull a bit over 2 amps when it starts up, the running amperage is much lower. I would expect that a full sized automobile battery would last all day if you were just running four Scalextric cars at a time. Chances are that the voltage would drop off gradually as time went by. You could minimize the drop-off by using a voltage regulator. As someone already mentioned it would be a good idea to fuse your track.
